> But they're interesting because they are laws - because there's some structure there, because the same causes consistently have the same effects. Superdeterminism denies all that.

Wait, how does it deny it?

> i'd say that if you're an inherent part of the causal chain that makes something happen then it's fair to say that you changed it. You don't have to assume free will to acknowledge that we affect our environment.

it's separating us from the environment and saying that one part changed the other, but that's just a simplification as our heads can't contain the whole system with all it's events. A blurry reflection. So now we "look" at this reflection and say : this is wrong, it makes no sense

Without simplification, we had some "initial" state and it "goes" somewhere. Like sand in a clock. We all know where the sand goes and what will happen in an hour.

We have words like "interesting, learn, understand" which don't really mean anything when we think about determinism. Science requires an observer but who is looking?

To be able to talk about cause and effect you have to have a concept of independence. Superdeterminism's basic premise is essentially that everything in the past can affect everything in the future - you chose which direction to measure because the particle was polarised a particular way (or because of some common underlying cause). So how can you possibly talk about what caused you to measure a particular direction when apparently it was magically due to this thing that has no visible connection to it?

And yet science does work. We're able to make predictions and see them borne out.

You mean a connection we can measure.

as i understand, our measurements rely on what we know and what we know relies on previous events. Its like what and how we measure something is simultaneosly determined by that something. We can't measure the size of a cat's soul because we don't have instruments for it but if we invent the instruments there will be no other choice than measuring them in a particular way the soul allows us to measure it.

Don't know if it make sense at all, but i tried to make sense of it.

Not necessarily that we can measure, but that we can reason about. We can't directly measure energy for example, but we know/assume that it obeys certain laws regarding conservation and locality.

If the cat's soul changed the usual laws of physics around the cat, it would destroy our ability to do physics when cats were nearby. It's not about whether we can measure it but about whether we can isolate its effects. If you can't do an experiment that doesn't depend on the state of the entire universe, you can't do an experiment.
